Be it known that I, EDGAR A. McALLIs TER, a citizen of the UnitedStates, residing at Baltimore, in the State of Maryland, have inventedcertain new and useful Improvements in Oarbureters, of which thefollowing is a specification.

This invention relates to carbureting devices in which aeriform iiuid iscarbureted.

Among the objects thereof is to provide an apparatus that will uniformlyand permanently carburet aeriform iiuid, properly regulate theproportions of the component parts, and produce an effective gas at theminimum 15 of carbon consumption. i

In the accompanying drawing the apparatus is shown in section, exceptthe compressor, pipes, and regulating-valves.

'Ihe letter A designates a gas-engine arzo ranged with acompression-cylinder ct to compress the atmospheric air.

B is the humidity-eliminator, C the carbureter, and D the gasometer.

From the compressor a a pipeE extends to l-`v and projects into theeliminator B. In this pipe E is arranged a safety-valve le to dischargeany excess of pressure, a regulatingvalve e to govern the amount ofpressure in the eliminator, and a diuser e2 to spray the 3o air beingdischarged into the eliminator. From the eliminator extends the pipe Fto the carbureteninto Which it projects nearly to the bottom. In thispipe F is a regulatingvalve f, which governs the amount of pres- 5 surecarried in the carbureter, and the lower end of the pipe F is providedwith a diffuser c' tp spray the air as it enters the hydrocarbon. Fromthe carbureter extends the pipe G to the gasometer,entering the latterat the bot- 4o tom and projecting above the liquid packing g. In thispipe is arranged a regulating-valve g to govern the amount of pressurecarried in the gasometer. From the gasometer extends the pipe H, whichfurnishes the supply of gas for consumption and to drive the engine A,the branch pipey h being provided with a governor h to govern the supplyof gas to the engine, said governor being connected by a pipe h2 to thepipe E between the regulating- L IO valve e' and compression-cylinder ctin order to regulate the Working of the engine in accordance with theamount of pressure carried in the eliminator B.

The engine A may be of any construction and actuated by steam or othersuitable means, butin this case I prefer using a gasengine, as the powertherefor can be derived from the product of the apparatus. Thecompression-cylinder ais of the usual kind, provided with a piston andinduction and eduction valves.

The humidity-eliminator B in this instance consists of a chamber b, inwhich the aeriform fluid is compressed, and a chamber b', which containssulfuric acid o7 or any suitable' absorbent. Between the two chambers isarranged a cut-0E valve b6 and a properly-constructed check-valve b2 toprevent any backiiow of the fluid. At the bottom of the chamber b isarranged an automatic discharge device consisting of a float b3, leverb4, and a valve b5, the latter being operated when the water eliminatedfrom the air reaches a given height by the float rising, which throughthe medium of the lever actuates the dischargevalve.

The carbureter C in this instance consists of a chamber c, whichcontains the hydrocarbon c2. The supply-pipe F extends nearly to thebottom of the carbureter and is provided at its lower end with adiffuser c to spray the aeriform'fluid as it is subjected to thehydrocarbon.

The gasometer Dis of the usual form, consisting of a fixed tank CZ and amovable tank d', with suitable liquid packing g to form a gas-tightjoint between the two tanks, the supply-pipe d2 and the discharge-piped3 connectin g with the chamber above the packing g.

The safety-valve, check-valve, regulatingvalves, and engine-governor areof the usual Well-known forms. Therefore a detailed description of thesame is unnecessary.

In the operation of the apparatus there being always sufficient gasretained in the gasometer B to start the engine, which is done in theusual manner, the air compressed by the compression-cylinder a passesthrough the pipe E, regulating-valves', and diffuser e2, where it entersthe chamber b of the eliminator B and is confined therein by the cutovalve b2 until from thirty to fifty pounds pressure is accumulated, thisamountof pressure being sufiicient to eliminate or exclude nearly allthe humidity from the aeriform iiuid, the humidity condensingand'accumulating at the bottom of the chamber. b, from which after apredetermined amount is accumulated it is discharged by the floatrising, which opens the valve b5 through the intervening lever b4. Assoon as succient Water has been discharged to lower the iioat thevalvejb5 is closed. Thus the accumulating Water is constantly beingdisposed of automatically. When the desired pressure is -accumulated inthe chamber b and the greater amount of humidity eliminated mechanicallyby the compression, the cut-off valve 196 is gradually opened, Which,allows the aeriform iiuid to pass to the chamber b of the eliminator'B,where it comes in contact with the sulfuric acid, which having a greataflnity for humidity, entirely eliminates any humidity from the aeriformfluid which might remain therein, leaving the same in condition tofreely and uniformly absorb the hydrocarbon and bring the molecules ofthe aeriform fluid and hydrocarbon in actual contact with each other.From the eliminatorB the fluid passes to the carbureter C through thepipe F and diffuser c at `the lower part of the chamber c andexpands'nto the hydrocarbon from thirty pounds pressure to iive pounds,(the amount carried in the carbureter,) which being free from humidityeffects a uniform and proper amount of hydrocarbon absorption necessaryto produce the desired combustion and economical consumption of thehydrocarbon. From the carbureter G the gas passes to the gasometer D,where it is again expanded and retained at about two pounds pressure,but as this second expansion takes place where there is no hydrocarbonto be absorbed the molecular parts although occupying a larger spacecontains the same amount of hydrocarbon as absorbed in the carbureter.From the gasometer the gas passes to the distributing-pipes ready forconsumption.

In case the compressor is supplying the aeriform fluid faster than theconsumption of the gas the increase of pressure in the pipe E acts onthe governor h and regulates the -supply of gas to just keep the engineA running. If under this condition the pressure still increases, thesurplus over the predetermined amount carried is discharged by thesafety-valve e.

By this apparatus a uniform and economical gas is produced andmaintained which will not condense or the component parts thereofseparate. The relative proportion of the parts can be accuratelyregulated toV produce gases containing from the minimum to the maximumamount of hydrocarbon, as desired, and the apparatus being practicallyself-actuating it requires only the minimum of labor kto operate thesame, thereby procuring economy both in attendance and consumption ofhydrocarbon, the latter being due to the proper proportions of thecomponent parts of the gas, due to the perfect regulation of theapparatus and the process and method therein employed.

Either of vthe elements disclosed may be greatly modified-that is, bydispensing with, adding to, or changing the form of the parts thereof.Therefore any modifications of the same are included with the claims.

A gasometer is shown and claimed in some of the combinations. It may,however, be dispensed with andthe pipe H act as an equivalent. Thereforesuch pipe is included as the equivalent of the Vgasometer. I

The process herein employed by which the carbureting is accomplished andthe method by which the relative proportions of the hy-v drocarbon andaeriform fluid are regulated I reserve for separate patents, theapplications for which were iled August 29, 1899, Serial Nos. '728,829and 728,830.
